Efficacy of Intralesional Candida Antigen Versus Measles, Mumps, and Rubella Vaccine Versus Topical Podophyllin in Treatment of Resistant Genital Warts.

BACKGROUND: No single treatment is ideal for genital warts with high rate of resistance using conventional modalities as topical podophyllin; however, several intralesional immunotherapies are being tested nowadays, with variable results. In this study, we compared the safety and efficacy of treating resistant and recurrent genital warts by 2 intralesional immunotherapies [Candida antigen and measles, mumps, and rubella (MMR) vaccine] and compared them with topical podophyllin. PATIENTS/METHODS: A total of 45 patients with resistant or recurrent genital warts were enrolled in this study. Size and number of warts were detected in each patient, patients were divided into 3 groups. Group A injected with intralesional Candida antigen. Group B with intralesional MMR vaccine. Group C were treated with topical 25% podophyllin. Patients received a session every 2 weeks for 3 treatment sessions. RESULTS: With regard to the reduction in size and number of all warts, the best response was obtained in Candida antigen group where 46.7% showed complete clearance and 40% showed partial response followed by MMR group and the last was the podophyllin group, with no significant difference between them. Complete clearance of mother warts was noticed in 86.7% of Candida group, 53.3% in MMR group, and last 40% in podophyllin group, with a significantly better response in the Candida group (P = .027). CONCLUSION: Both intralesional Candida antigen and MMR vaccine are simple, safe, and effective treatment options with comparable results and better response than topical podophyllin.

Intralesional measles, mumps, and rubella vaccine after failure of intralesional Candida antigen for the treatment of recalcitrant pediatric warts.

Numerous studies have investigated the efficacy of intralesional immunotherapy for warts, but there are a lack of studies investigating the efficacy of alternative intralesional immunotherapies following failure of initial intralesional immunotherapy. In this retrospective study, we aimed to investigate the efficacy of intralesional measles, mumps, and rubella vaccine for the treatment of pediatric warts following failure of intralesional therapy with Candida antigen. Following intralesional measles, mumps, and rubella vaccine administration, 8/51 (15.5%) patients had complete resolution of their warts, 6/51 (12%) had near complete resolution, 19/51 (37%) had partial improvement, 12/51 (23.5%) had no change, and 6/51 (12%) had worsening. Although limited by retrospective nature and low sample size, our results demonstrate that intralesional immunotherapy with measles, mumps, and rubella vaccine provides an alternative therapeutic option for the treatment of recalcitrant pediatric warts in patients who fail to respond to intralesional Candida antigen.

Immunization with Pneumocystis carinii A121-85 antigen activates immune function against P. carinii.

BACKGROUND: Pneumocystis pneumonia (PcP), which is caused by Pneumocystis carinii, is a life-threatening infection that affects immunocompromised individuals. Unfortunately, chemoprophylaxis and dapsone are only effective for half of the patients with PcP, indicating that additional preventive methods are needed. We predicated the pneumocystis surface protein A12 sequence 1-85 by DNAStar software and BepiPred, and identified it as a potential vaccine candidate by bioresearch. METHODS: We used recombinant A121-85 as antigen to immunized mice and detected serum titer of IgG, expression of inflammatory factors by EILSA, qRT-PCR and flow cytometry. RESULTS: Our results showed that immunization with recombinant A121-85 increased the serum titer of IgG, promoted the secretion of T lymphocytes, increased the expression of inflammatory factors, and elevated lung inflammatory injury in mice. CONCLUSIONS: Our findings suggest that A121-85 is a potential vaccine target for preventing Pneumocystis carinii. The evaluation of A121-85-elicited antibodies in the prevention of PcP in humans deserves further investigation.

Intralesional Antigen Immunotherapy in the Treatment of Periungual Warts.

BACKGROUND: Intralesional immunotherapy using different types of antigens is considered an effective and safe treatment option for different types of warts. However, there are few studies that illustrate the use of these antigens in the treatment of periungual warts as a distinct type of warts. OBJECTIVE: To evaluate the efficacy and safety of three antigens: measles, mumps, rubella (MMR) vaccine, Candida antigen, and purified protein derivative (PPD) in the treatment of periungual warts. METHODS: The study included 150 patients who were randomly assigned to 3 groups with 50 patients in each. Each agent was injected intralesionally at a dose of 0.1 mL into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions. RESULTS: Complete clearance of warts was observed in 70%, 80%, and 74% in PPD, Candida antigen, and MMR vaccine groups, respectively. There was no statistically significant difference regarding the therapeutic response between the 3 studied groups. Adverse effects were transient and insignificant in the 3 groups. No recurrence of the lesions was reported in any of the studied groups. CONCLUSIONS: Intralesional antigen immunotherapy seems to be an effective therapeutic option for the treatment of periungual warts.

Successful treatment of recalcitrant molluscum contagiosum in a stem cell transplant patient with Candida immunotherapy.

Solid organ and stem cell transplant recipients have an increased risk of developing cutaneous infections, which often are refractory to conventional treatment (Euvrard et al., Journal of the American Academy of Dermatology, 2001, 44, 932-939). Molluscum contagiosum, a common self-limited disease primarily affecting children, can be more severe and unresponsive to therapy in transplant patients (Gardner & Ormond, Clinical and Experimental Dermatology, 2006, 31, 452-453). Candida immunotherapy has been widely used for the treatment of warts, and recently its application has been expanded to include treatment of symptomatic molluscum in pediatric patients (Enns & Evans, Pediatric Dermatology, 2011, 28, 254-258; Maronn et al., Pediatric Dermatology, 2008, 25, 189-192). However, to our knowledge there have been no reports in the literature of its utility in the setting of adult transplant or immunocompromised patients. Herein, we report a case of successful treatment of refractory molluscum contagiosum in a stem cell transplant patient with Candida immunotherapy.

Peripheral blood toll-like receptor 4 correlates response to candida immunotherapy of warts.

Human papilloma virus infection may be self-limiting; however, some cases may spread. There are no factors predicting the prognosis of such infections. The present study aimed to evaluate the significance of TLR4 expression in predicting the response of warts to candida immunotherapy. A total of 60 patients with different types of warts were included in the present study. A total volume of 2 ml venous blood was collected and real-time polymerase chain reaction was used to determine expression of TLR4. Patients were subjected to intralesional injection of Candida antigen into the largest wart at 2-week intervals until complete clearance or for a maximum of six sessions. Of the total 58 patients available for analysis of study results, 44 patients (75.9%) showed complete resolution with better response in younger ages. The TLR4 expression in patients with complete and partial response was significantly higher than that in patients who had no response (p = .006). Among our patients, 48.3% showed no side effects, 44.8% showed local reactions, and 6.9% showed systemic side effects. Only four patients showed recurrence after 6 months. Using receiver operating characteristic curve analysis, at cutoff of expression level >12 is accompanied by 100% specificity of TLR4 in predicting treatment response to candida immunotherapy. Candida immunotherapy is an effective warts treatment, especially in young patients. Higher PMBC TLR4 levels can predict response to candida immunotherapy.

Uveitis Following Treatment of Verruca Vulgaris with Intralesional Candida Antigen.

[THE CORRECTION OF THE LOCAL IMMUNE RESPONSE AT THE PATIENTS WITH HELICOBACTER PYLORI INFECTION].

INTRODUCTION: Helicobacter pylori infection is due to the high prevalence in population attracts the clinical interest of researchers in the whole World. It is well known that this microorganism not only resides in the mucosa of the gastrointestinal tract, but is also defined in the periodontal pocket of the oral cavity. THE AIM OF INVESTIGATION: to evaluate Helicobacter pylori diagnostics in the mouth and prove a method of relief of the inflammatory process by applying immunomodulator Imudon. RESULTS. On the basis of obtained results it was found that the inclusion of topical immunomodulator Imudon in the complex therapy of Helicobacter pylori-associated diseases leads to reduction of inflammatory potential through the decrease of the TNFα, IL-6 activity in saliva and to increase the protective properties of saliva as a result of increased levels of mucin, significantly reduces the frequency of relapses in the one year after therapy. CONCLUSION: It is practically important to determine the effectiveness of eradication therapy by the study of the contents of the tooth-gingival pocket for the detection of genetic material of Helicobacter pylori, as well as to include in the complex therapy of Helicobacter pylori-associated diseases of the immune modulator Imudon.

TLR3 essentially promotes protective class I-restricted memory CD8⁺ T-cell responses to Aspergillus fumigatus in hematopoietic transplanted patients.

Aspergillus fumigatus is a model fungal pathogen and a common cause of severe infections and diseases. CD8⁺ T cells are present in the human and murine T-cell repertoire to the fungus. However, CD8⁺ T-cell function in infection and the molecular mechanisms that control their priming and differentiation into effector and memory cells in vivo remain elusive. In the present study, we report that both CD4⁺ and CD8⁺ T cells mediate protective memory responses to the fungus contingent on the nature of the fungal vaccine. Mechanistically, class I MHC-restricted, CD8⁺ memory T cells were activated through TLR3 sensing of fungal RNA by cross-presenting dendritic cells. Genetic deficiency of TLR3 was associated with susceptibility to aspergillosis and concomitant failure to activate memory-protective CD8⁺ T cells both in mice and in patients receiving stem-cell transplantations. Therefore, TLR3 essentially promotes antifungal memory CD8⁺ T-cell responses and its deficiency is a novel susceptibility factor for aspergillosis in high-risk patients.

[Local immunomodulating agents in complex treatment of oral lichen planus].

The paper presents the results of local immunity status assessment in patients with erosive-ulcerous form of oral lichen planus by etiopatogenetic treatment including imudone and derinate. The positive dynamics of immunological parameters under imudone and derinate is demonstrated.

Finger Necrosis After Cutaneous Wart Intralesional Injection with Candida albicans Antigen: A Case Report.

CASE: A 25-year-old man presented 18 hours after Candida albicans antigen injection into a left index finger cutaneous wart by his dermatologist. He experienced a rapid-onset inflammatory response, which was indistinguishable from gangrenous infection. Urgent incision and drainage was performed; however, no purulent collection was noted and no organism isolated. At 1-year follow-up, he made a full recovery. CONCLUSION: Intralesional C. albicans antigen injection in digital cutaneous warts may cause an exaggerated immune response resulting in partial necrosis of the finger pulp. The clinical presentation may be difficult to distinguish from coexisting infection, but in some cases, observation may be an appropriate course of action.

[Immune reactions of palatine tonsils in the patients with chronic tonsillitis and the possibilities for their immunological rehabilitation with the use of imudon].

The objective of the present study was to develop a rationale for the application of imudon (a bacterial lysate preparation)in the treatment of the patients presenting with chronic tonsillitis based on the elucidation of characteristics of local immunity in the oropharynx (determined from the results of cytograms, immunoenzyme assays for the quantitation of IgG, sIgA, IgA, and IgM antibodies, and calculation of the relative secretion coefficients). A total of 74 patients with chronic tonsillar pathology (24 children and 50 adults) were available for the observation along with 42 subjects having no tonsillar pathology with concomitant chronic bacterial rhinosinusitis. The control group was constituted by 25 practically healthy subjects. It was shown that the local application of imudon in the patients with the preserved function of palatine tonsils (in the absence of symptoms of chronic inflammation) produces the adequate response of the humoral and cellular immunity systems. In the patients with the simple form of chronic tonsillitis imudon therapy ensured statistically significant activation of congenital immunity including the phagocyte function and a tendency toward normalization of antibody formation. It is concluded that alteration of the function of palatine tonsils in the patients presenting with the toxico-allergic form (ТАФ-2) of chronic tonsillitis implies the necessity of surgical treatment (tonsillectomy).

Intralesional immunotherapy for the treatment of anogenital warts in pediatric population.

BACKGROUND: The prevalence of anogenital warts is increasing in adults as well as in pediatric population. The treatment of anogenital warts is challenging, particularly in children as most conventional modalities are painful and associated with high recurrence rates. OBJECTIVES: To evaluate the efficacy and safety of intralesional immunotherapy for the treatment of anogenital warts in pediatric patients. METHODS: Forty child presenting with multiple anogenital warts were randomly assigned into 3 groups. The first group (15 patients) received intralesional MMR vaccine, the second group (15 patients) received intralesional Candida antigen and the third group (10 patients) received intralesional saline as a control. Each modality was injected into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions. RESULTS: Highly significant difference was found between the therapeutic response of anogenital warts to both MMR vaccine and Candida antigen compared to intralesional saline (p = .005). No significant difference was observed between MMR vaccine and Candida antigen groups (p = .885). Side effects were mild and no recurrence was detected in the 6 month follow-up period. CONCLUSIONS: Intralesional immunotherapy is a promising effective and well-tolerated treatment modality for multiple anogenital warts in children.

Immunotherapeutic modalities for the treatment of recalcitrant plantar warts: a comparative study.

BACKGROUND: Plantar warts are sometimes resistant or they tend to recur after every possible destructive therapy. Immunotherapy has been used as a promising alternative therapeutic option in such recalcitrant cases. AIM: To evaluate and compare the efficacy and safety of the intralesional injection of vitamin D3, zinc sulfate 2%, and Candida antigen in the treatment of recalcitrant plantar warts. PATIENTS AND METHODS: The study included 152 adult patients with single or multiple recalcitrant plantar warts. They were equally subdivided into four groups (38 patients in each): 2% zinc sulfate, vitamin D3, Candida antigen, and normal saline respectively. Injections were done at 3-week intervals until complete resolution or for a maximum of 4 sessions. RESULTS: Complete response was achieved in 20 patients (52.7%) of the zinc sulfate group, 34 patients (89.5%) of the intralesional vitamin D3 group, 25 patients (65.7%) of the intralesional Candida antigen group and 8 patients (21.2%) of the saline group. The difference between the groups was statistically significant in favor of vitamin D3 (p = .037). CONCLUSIONS: Recalcitrant plantar warts were best treated with vitamin D3 that also has the advantages of better response on distant warts, minimal side effects, and low rate of wart recurrence.

Mycobacterium avium complex and Cryptococcus neoformans co-infection in a patient with acquired immunodeficiency syndrome: a case report.

INTRODUCTION: Opportunistic infections (OI) are common in patients with acquired immunodeficiency syndrome (AIDS). Cryptococcus neoformans and Mycobacterium avium complex (MAC) are frequently responsible of such infections. However, concurrent infection with these two pathogens is uncommon and underreported in the literature. CASE DESCRIPTION: We describe the case of a 28-year-old Caucasian Belgian patient with no travel history, who presented with low-grade fever, headache and wasting syndrome. He was diagnosed with human immunodeficiency virus (HIV) infection at AIDS stage, with a HIV viral load of 506,000 viral copies/mL and a CD4 + T-cells count of 10 cells/µL. Diagnosis of disseminated Cryptococcus neoformans infection was made by positive serum cryptococcal antigen and positive culture for Cryptococcus neoformans in blood and in cerebrospinal fluid. Diagnosis of disseminated Mycobacterium avium complex infection was made by positive culture on a biopsy of a mediastinal lymph node. With adequate anti-retroviral therapy (ART) and treatment of these OIs, the patient recovered well and had a good clinical evolution. DISCUSSION AND CONCLUSION: To our knowledge, this is the second case of coexistence of these two dangerous OIs reported in the post ART era. Clinicians should be aware that such co-infections still happen in high-income countries, in patients with severe immunodeficiency. Early detection and treatment of HIV is of paramount importance to prevent AIDS and its complications. We highlight the importance of thoroughly excluding all opportunistic infections in patients with newly diagnosed AIDS.Abbreviations: ABC: abacavir; AIDS: acquired immunodeficiency syndrome; AFB: acid-fast bacilli; ART: antiretroviral therapy; CM: cryptococcal meningitis; CrAg: cryptococcal antigen; CSF: cerebrospinal fluid; CT: computed tomography; EACS: European AIDS Clinical Society; FTC: emtricitabine; HIC: high-income countries; HIV: human immunodeficiency virus; HIV-VL: HIV-viral load; ICP: intracranial pressure; IRIS: immune reconstitution inflammatory syndrome; MAC: Mycobacterium avium complex; MRI: magnetic resonance imaging; MSM: man who has sex with men; NR: normal range; OD: omne in die = once daily; OI: opportunistic infection; RAL: raltegravir; TAF: tenofovir alafenamide fumarate.

Intralesional Candida antigen versus intralesional vitamin D3 in the treatment of recalcitrant multiple common warts.

BACKGROUND: There are various therapies available for recalcitrant common warts; however no specific therapy has been established as entirely effective. AIMS: To assess the efficacy and safety of intralesional Candida antigen injection of vs. intralesional vitamin D3 injection in the treatment of multiple recalcitrant common warts. PATIENTS AND METHODS: A total of 80 adult patients with multiple common warts were randomly assigned to one of three groups in this study. Thirty patients were assigned to Group I, who received a 0.3 ml intralesional injection of Candida antigen. Thirty patients were assigned to Group II, who received a 0.6-ml (60 000 IU) intralesional injection of vitamin D3. Twenty patients were in Group-III, who received 0.3 ml of normal saline as a control. Each agent was injected at the base of largest wart every 3 weeks until full clearance has been obtained, or for a maximum of four sessions. RESULTS: In the Candida antigen, vitamin D3, and saline groups, complete wart clearance was observed in 76.7 percent, 20%, and 0.0 percent, respectively. The side effects were negligible and transient, and there was no recurrence of the lesions. CONCLUSION: Intralesional injection of Candida antigen is as a safe, simple, cost-effective treatment modality for multiple recalcitrant common warts and it outperforms intralesional vitamin D3.

[Economical evaluation of the treatment of invasive aspergillosis in pediatric oncology patients. Santiago. Chile]. / Estudio de costo del tratamiento de la aspergilosis invasora en pacientes oncológicos pediátricos. Santiago. Chile.

INTRODUCTION: Invasive aspergillosis (IA) is a serious opportunistic infection in immunocompromised patients. Transplant recipients and patients with cancer represent the highest risk group. The antifungal treatment involves prolonged hospitalization and high economic resources. OBJECTIVE: to estimate costs represented by IA as an intercurrent complication of oncologic treatment. PATIENTS AND METHOD: Retrospective case-control study. Estimation of the cost of treatment in pediatric oncologic patients with IA in the Hospital Luis Calvo Mackenna during the years 2007-2008 was done. A control for each case of IA paired by sex, age, number of diagnosis and clinical department was selected. RESULTS: There were 13 patients during the observation period. The attributable cost of treatment of aspergillosis was US $23,600 and the cost for each indicator was: hospital days US $16,500; antifungal therapy US $7,000; and serum galactomannan US $100. DISCUSSION: In this study, the cost of treating IA is mainly due to hospitalization and antifungal medications. Three patients acquired IA in spite of staying in a protected environment.
